HOW TO CONTROL THE 
BOLL WEEVIL 

SYRUP (OR MOLASSES) AND CALCRJM ARSENATE 

or 
DRY OR DUSTED CALCIUM ARSENATE 

WHICH? 



In undertaking this treatise on the boll weevil, I will en- 
deavor to make it as full and comprehensive as possible. 

My prime object is to bring about a standardization of 
syrup or molasses as a basis for applying calcium arsenate to 
control the weevil. With this accomplished it will be an easy 
matter to convince the cotton planter that this is the best 
method yet discovered for controlling this pest. 

The first step is to place these facts before the people most 
interested and it will then be readily understood why all 
farmers do not secure the same results when demonstrating the 
syrup or molasses method. 

I present to the readers of this paper, the opinions of the 
best authorities of the U. S. Government Entomological de- 
partment and reprint the report as made by the chief U. S. 
station in the South at Tallulah, known as the Delta Labora- 
tory, the highest authority on the boll weevil. 

ORIGIN OF THE BOLL WEEVIL 

The boll weevil originated in Mexico and has progressed 
northward until the infected area encompasses almost the en- 
tire cotton belt; the exception being parts of Oklahoma, Ar- 
kansas, Tennessee and North Carolina, where, as yet, the wee- 
vil has not become sufficiently acclimated to stand the rigors of 
winter. Even in the valleys of the most northernly cotton 
states, the weevil has done but little damage, except in certain 
localities. 



HOW FAST BOLL WEEVILS MULTIPLY 

Many a farmer excuses his indifference for the welfare of 
his crop by deluding himself into the belief that there are but 
few weevils in his growing crop, when the truth is that when 
his cotton is young and apparently a few weevils have ap- 
peared that it then is in the greatest danger. I w^ill say as a 
basis of illustration, when he has five hundred weevils to the 
acre giving June 20 as the starting point, that by November I 
there would be many hundred millions per acre. According 
to Professor Hunter in Bulletin 512, page 12: "A conservative 
estimate of the possible progeny of a single pair of weevils 
during a season beginning June 20, and extending to November 
4, is 12,755,100 weevils." 

So, it can readily be seen according to this increase, by 
geometrical progression, that it is the last three crops of w^eevils 
that put the finishing touches of destruction on the prospects 
of the farmer who has fooled himself into believing that he 
alone is going to escape the ravages of the pest because he has 
"not sufficient weevils to hurt," but when two-thirds of his 
labor has been destroyed by them, and when it is too late, he 
awakens to realize that as a result of his procrastination and 
indifference he had lulled himself to sleep on a false premise. 

Professor Coad, in his bulletin No. 731, July 19, 1918, 
page 1 5, says: "The weevils on emerging in the spring will 
always concentrate near the hibernation quarters in which they 
spent the preceding winter. They remain rather closely at 
these points until they have multiplied sufficiently to threaten 
a shortage of food supply" (by exhausting the squares). "For 
this reason a great part of the cotton is not seriously infected 
with weevils until some time after midseason and often not 
until August." 

DESTROY THEM EARLY 

I am spending my own money to bring the average cotton 
farmer to a realization of the fact that he is wasting ten times 
as much labor raising cotton upon which to feed boll weevils 
as it would take to destroy them in the early spring as they 
emerge from their winter quarters to begin their career of 
devastation.

THE EFFICACY OF POISONED MOLASSES MIXTURE 

FOR THE CONTROL OF THE COTTON 

BOLL WEEVIL 

By B. R. Coad. 

During the past few weeks there has been considerable 
interest in certain portions of the cotton belt relative to the 
possibility of poisoning the cotton boll weevil by using a mix- 
ture of molasses, calcium arsenate and water. Numerous in- 
quiries have been recived concerning the efficacy of such a 
mixture and so many reports were noted of excellent results 
being secured in field use that it was deemed desirable to give 
the question rather serious consideration. No experiments had 
been conducted by the Department of Agriculture with this 
particular mixture but years ago numerous tests were conducted 
to determine the possibility of attracting weevils with a large 
number of sweets including molasses and the results were gen- 
erally negative, although there were a few instances of a very 
slight degree of attraction being shown. In view of these re- 
sults it had seemed useless to conduct any further tests along 
this line until the present interest developed. 

The first series of tests consisted of cage studies com- 
paring the weevil mortality on plants treated with the molasses 
mixture, plain dusted calcium arsenate and also unpoisoned 
check plants. Various concentrations and amounts of the mo- 
lasses mixture were tested and the entire series was repeated 
five times. In all a total of 86 different cage tests, involving 
the use of about 1200 w^eevils, were included in these series. 
The first test conducted showed the average mortality pro- 
duced by the molasses mixture to be exactly the same as that 
of dusted calcium arsenate. The second show^ed the dusted 
calcium arsenate to be superior, while the third series indicated 
about an equal superiority of the molasses mixture. The 
fourth test was slightly in favor of the dusted calcium arsenate 
while the fifth showed the two preparations to have about an 
equal degree of toxicity. The average of the entire series 
showed the mortality in all cnges treated with dusted calcium 



arseniiie to be exactly ihe same as that in the cages treated with' 
(he molasses mixture. 

Tests of different amounts of the molasses mixture and 
also variations in the distribution over the plant showed prac- 
tically no relation between these variants and the resultant 
mortality. In other w^ords, the weevil mortality was prac- 
tically as great in the cage receiving the lightest doses as in those 
receiving the heaviest. 

The next series of tests were conducted on more nearly 
a field basis. For the purpose of these tests five rows of cotton 
were treated with the molasses mixtures, the next five with 
dusted calcium arsenate and the next five left untreated as a 
check. These three conditions were repeated three times in 
each experiment, thus making a total of I 5 rows receiving each 
type of treatment in each test. The entire test was repeated 
four times under different field conditions. After the treat- 
ment these rows were examined carefully once a day for three 
days and the number of live weevils found on each row was 
carefully noted. The first series showed a very definite con- 
trol reaction for the molasses mixture and indicated that much 
benefit had been derived from the application. Of the re- 
maining three series, however, two showed more mortality in 
the rows treated with calcium arsenate than in those treated 
with the molasses mixture. In the four series as a w^hole there 
is no striking difference between the different treatments. 

To secure a still further check from this subject a series 
of field plat tests were started, uniform cuts being surveyed, 
divided in half and one-half treated wich dusted calcium arse- 
nate while the other was treated with the molasses mixture. 
These tests are still under way but the results to date are of 
interest. The central 1 rows in each plat have been exam- 
ined daily and the number of live weevils found on them care- 
fully noted, as well as the percentage of squares punctured. 
To date we have found no definite difference in the square 
infestation and the record of live weevils collected shows al 
most three times as many found on the plats treated with mo- 
lasses as on those treated w^ith dusted calcium arsenate. 

Considering these records as a whole it is seen that the 
molasses mixture does exercise a certain degree of control over 
the boll weevil but that this is generally less than that secured 
with plain dusted calcium arsenate. Under certain conditions 
it was found that a much tetter degree of control was secured 
from the molasses mixtm-e than v^^ith calcium arsenate, but this 
result was noted only in the case of very small cotton plants 
averaging only a few inches in height, and also only during 
exceedingly dry weather. The latter fact was particularly 



noticeable and is probably the key-note of the variaticm in 
results. 

It seems quite probable that during exceedingly dry 
weather the weevils visit the droplets of molasses-water mix- 
ture for the purpose of securing moisture but do not follow 
this practice to as marked a degree during normal weather. 
In other words, the results so far indicate that dusted calcium 
arsenate is superior to the molasses mixture except during ex- 
ceedingly dry weather and on very small plants. At the pres- 
ent time the growth qf the cotton plants has apparently reached 
the point where the molasses mixture does not give any marked 
degree of control. Our fairly large scale applications on an 
acreage basis showed that it takes at least one hour and a half 
to treat one acre of small cotton with the molasses mixture and 
thb would make the labor cost of the application somewhat 
greater than that involved in applying the plain dust. In view 
of such results there seems to be little reason for using the 
molasses mixture in preference to plain calcium arsenate at any 
time and it certainly should not be used on the cotton plants 
after they reach the squaring stage. 

EDITOR'S NOTE— 

I regard the cage test of Professor Coad to be a fair one 
as to the syrup (or molasses) and calcium mixture, inasmuch 
that it proves the local attracting power of syrup (or molasses) 
and calcium arsenate and that it did kill the weevils by their 
hunting for it, and eating it, but in the case of the dusted cal- 
cium arsenate it stands to reason that if weevils are confined 
to a cage and this confined atmosphere is in a measure sur- 
charged with calcium arsenate that there would be a small 
chance of escape from its deadly effects and that even though 
the weevil did not eat this dry or dusted calcium arsenate, the 
still atmosphere being thus surcharged with the deadly poison, 
there could be no other result reasonable except to kill him. 
I cannot agree with the comparative reports of the paper of 
Professor Coad as proving that dry or dusted calcium arsenate 
is anything like as effectual as syrup (or molasses) and cal- 
cium arsenate processes, when the proper kind of syrup (or 
molasses) is used with calcium arsenate. 



That these points might be cleared up to my satisfaction, 
I addressed the following letter to Professor Coad: 

Ensley High School, 
Ensley, Alabama, 
September 20, 1921. 
Professor B. R. Coad, 

Tallulah, La. 
Dear Sir: 

I have read with much satisfaction your paper of July 6, 
1921, on the use of syrup or molasses and calcium arsenate 
for controlling the boll weevil, and note your suggestion that 
the syrup or molasses mixture is more efficacious when applied 
to young cotton and when the plant is small. 

Will you please give me the exact formula of the syrup 
mixture you used in the cage tests. I do not regard the field 
tests as being of any great importance since only a portion of 
a patch of cotton was used for the demonstrations as it is my 
opinion that a fair field test could not be made except that it 
had been applied to the entire patch or cut of cotton and this 
cut completely isolated from any other cotton. 

In applying the dusted calcium arsenate in the cage tests, 
were the cages closed practically air tight, or were they suf- 
ficiently open to prevent the surcharging of the atmosphere 
with the dusted calcium arsenate? 

I do not w^rite this in a spirit of criticism, but to gain in- 
formation upon which to base my ow^n conclusions as to the 
relative value of the two methods of applying the calcium ar- 
senate for weevil destruction. 

It is my opinion that your valuable paper of July 6, 1921, 
should have wide circulation so that the cotton planter might' 
be prepared to apply the syrup and calcium arsenate early next 
summer, while the cotton is small (the atmosphere generally 
being dry at that period of the year) and destroy the first crop 
of weevils as they emerge from hibernation. 

I note also at the close of your paper of July 6, 1921, 
that you use the language "It certainly should not be used on 
the cotton plants after they reach the squaring stage." (Mean- 
ing the molasses and calcium arsenate mixture.) Will you 
please explain what is meant by this paragraph and from 
whence you draw your conclusions, etc. ? 

Thanking you for a reply at your earliest convenience, 
I am Yours very truly, 

WM. J. MIMS.

To this letter I received the following reply: 

Tallulah, La.. Sept. 24, 1921. 
Mr. Wm. J. Mims, 
Ensley High School, 
Ensley, Ala. 
Dear Sir:— 

We have your letter of the twentieth and answering your 
inquiries chronologically will say, first, that the formula of the 
syrup mixture used in the cage test to which you refer was 
as follows: 

Yl gal- water. 

2 lbs. calcium arsenate. 

I gal. molasses. 

Second, in applying the dust (calcium arsenate) in these 
cage tests, would say that they were not enclosed at all, the 
calcium arsenate being applied with a duster (hand gun) in 
the same manner as to the cotton plant in our field tests. 

Third, concerning the admonition contained in the last 
paragraph of circular dated July 6th, 1921, our conclusions 
were based upon the actual results obtained in these tests; that 
is to say, after the plant reached the squaring stage it was no- 
ticeable that the molasses mixture lost its control of the weevil. 
Very truly yours, 

GEO. A. MALONEY, 

In Charge Advisory Division, 
Delta Laboratory. 

SOLUTION TOO BITTER 

The mixture according to the above formula was entirely 
too strong. Such excess of calcium arsenate makes a solution 
that repels the boll w^eeil instead of attracting him. He would 
not eat or drink anything quite so bitter except in case of great 
hunger or thirst. According to the best reports I have received 
from successful experiments this solution contains about three 
times as much poison as it should in order to be most effective. 

WHEN TO APPLY 

When the cotton is from ten to twenty- four inches high 
and the squares are just beginning to form is the time when 
it is first attacked by the weevil as he is then just coming out 
of his winter hiding place (hibernation), and will begin to lay 
the first eggs. When these eggs begin to hatch at the end of 
the first twenty- one- day period this is called the first crop of 



weevils. If the first crop of weevils is destroyed, a second ap- 
plication will catch all which may have escaped the first appli- 
cation and also the young ones which may be hatched from the 
first few squares punctured. This will insure a fair cotton crop. 
Sometimes in extreme cases a third application would be nec- 
essary to insure a full cotton crop. 

HOW TO APPLY 

Make a small rag mop with a handle about sixteen or 
eighteen inches long, and apply poison to small cotton by a 
sweeping motion across the stalks. In large cotton make an 
upward stroke through the branches, endeavoring to get it 
under the leaves and on the tender parts of the stalks. One 
man can apply to two rows at a tinae about as fast as he can 
walk along between them. The poison does not have to be 
on both sides of the same stalk of cotton, although this would 
be better. 

COST OF LABOR 

The labor for applying the syrup and calcium arsenate 
cannot well be considered, since each planter must settle this 
problem for himself, but generally speaking, the cost of labor is 
not an item to be calculated in applying poisons to cotton, 
because the labor used is the same labor that made the crop 
and as the crop is practically "laid by" when the labor for 
applying is needed, it costs practically nothing; but the average 
negro tenant and share hand cannot be induced to handle the 
dusted calcium arsenate while no trouble whatsoever is ex- 
perienced in getting them to apply syrup and calcium arsenate. 
This item alone is of sufficient importance to weigh heavily in 
favor of using syrup and calcium arsenate in preference to the 
arsenate in the dusted form, even if their efficacy were proven 
to be equal. 

DIFFERENCE IN TIME TO APPLY 

The syrup and calcium arsenate can be applied at any 
time of the day, while the dusted calcium should be applied in 
the late evenings, at night by moonlight, or in the early morn- 
ings, when the atmosphere is still and when the cotton plant is 
moist with dew. Thus, the cost of labor is in favor of the 
solution rather than the dust, to say nothing of the difference 
in the cost of an application per acre, and in the cost of the 
apparatus for applying. 

HOW TO CONTROL THE WEEVIL 

There are only two accepted theori«at as t« the best 

1@ 



method of controlling the weevil. Both are to reduce the 
damage by reducing the number of weevils, as it is generally 
conceded to be practically impossible to eradicate the pest 
entirely, owing to his hibernating habits and rapid spread, as 
indicated in the foregoing paragraph on the origin and habits 
of the w^eevil. 

DUSTED CALCIUM ARSENATE REPELLANT 

The first method is to treat the cotton with calcium arse- 
nate in the dust form; that is, to apply it as a powder to the 
plants. To apply it thus with any degree of success the work 
of putting it on the plants must be performed in the early 
morning, late in the afternoon or at night, when there is suf- 
ficient dew on the cotton to prevent the calcium arsenate in 
this light form from stifling those applying it. Also the atmos- 
phere must be comparatively still as only a slight wind will 
drive it away and cause great w^aste. 

The effect of this nature of applying calcium arsenate is 
to repel the w^eevils. Consequently many of them flee from 
the cotton patch being treated and hie themselves to the weeds, 
ditch banks, turning rows, or nearby woods, to remain until 
come merciful rain shall come and wash aw^ay the calcium arse- 
nate from the cotton stalks, leaves and squares, so that they 
may return to their natural breeding ground, the cotton square 
and boll. 

SYRUP AND CALCIUM ARSENATE AN ATTRACTION 

The other method of applying calcium arsenate is to mix 
it with syrup or molasses. This kind of mixture can be applied 
at any time, day or night, and by applying it under the leaves 
and along the tender parts of the stalks, it does not repel the 
weevils, but on the contrary it attracts them and at the same 
time it also attracts those that may be in the weeds along the 
ditch banks, turning rows, or nearby weeds, and they too are 
extervninated as rapidly as they are attracted. 

RELATIVE COST OF THE TWO METHODS 

Analyzing the two methods it is easy for the cotton 
planter to decide in favor of syrup (or molasses) and calcium 
arsenate. In another paragraph I have shown that the relative 
cost of labor for applying by either of the methods is prac- 
tically the same, but the cost in material is greatly in favor of 
using the syrup or molasses mixture. The cost of material per 
acre for three applications in one season is approximately as 
follows: syrup (or molasses) and calcium arsenate, $1.20; 

11 



calcium arsenate in dusted form, $4.75; making a difference of 
$3.55 in favor of syrup (or molasses) and calcium arsenate — 
or sufficient to pay all the cost of labor for the three applica- 
tions of syrup and calcium arsenate. 

The syrup or molasses method needs no machine for 
spraying, hence the cost of machines for putting on the dusted 
calcium arsenate must be taken into consideration and this cost 
to the small farmer is no little item. But as I have before 
stated, the cotton farmers can figure out their own labor prob- 
lems, since no two of them in any community are likely to be 
similarly situated as to the labor making the cotton and as to 
its relative control when needed. 

SAVE THE BOTTOM CROP 

Professor Hunter, in "Boll Weevil Problem," Bulletin No. 
512, page 25, says: "They are unable to breed until squares 
are put on by the plants. 

"Under usual conditions they will multiply until the crop, 
put on after a certain date, will all be destroyed. This, how- 
ever, is of no importance since a top crop in weevil regions is 
entirely out of the question." 

Here is conclusive evidence that if the weevil is destroyed 
as he emerges from winter quarters where he lies dormant 
throughout the winter months that the bottom cotton crop will 
be saved. Indeed it is my opinion that three applications will 
rave the entire crop if properly and systematically applied and 
if a good uniform grade of both molasses and calcivun arsenate 
are employed. 

SORGHUM MOLASSES 

Sorghum molasses should not be used under any circum- 
stances, nor should syrups containing certain acid elements be 
used. The highest grade of syrup usually produced from seed- 
less sugar cane will accomplish good results w^hen new, but the 
using of old syrups should be avoided. The musty smell and 
taste of re-boiled or old syrups are not attractive to the wee- 
vils and should not be used. Any comparatively new uniform 
molasses will accomplish the desired results if properly applied. 

CAUSE OF FAILURE 

The failure of many of the tests and demonstrations made 
of syrup and molasses is to be laid to the inferior or adulter- 
ated calcium arsenate and many failures can also be attributed 
to old musty syrup or molasses and to using sorghum. 1 be- 
lieve that some way will be found to standardize the syrups or 

12 



molasses and calcium arsenate and thus insure the experiments 
that are made to all be upon the same basis. But even then 
the indifference of some farmers and the differences in judg- 
ment of others as to the proper time to apply will bring about 
various results from the same mixture. The using of inferior 
syrups (or molasses) and calcium arsenate has caused enough 
failures in demonstrations to entirely discredit this method with 
many people. When a standard is adopted for both the cal- 
cium arsenate and the syrup used, I believe that the boll weevil 
will be as quickly eradicated as was the army worm. 

TIME TO APPLY SYRUP MIXTURE 

As already stated syrup and calcium arsenate as a weevil 
exterminator has passed the experimental stages. If it is ap- 
plied in the early spring as before directed it is an easy matter 
to save a cotton crop. Do not wait to find if you have weevils, 
for if they were with you this season they will be with you 
next, even in greater numbers, 

BOLL WEEVIL— BOLL WORM 

Entomologists generally agree that the boll weevil does 
not do all the damage to fully matured bolls, but the boll worm, 
which is an entirely different species of pest, creates much of 
the havoc to full grown bolls and has done so for many years; 
but by growing a stock of corn about every twelve feet each 
way, in the cotton, this worm which has much more of a liking 
for corn than for cotton, will be attracted from the cotton and 
his damage can be almost entirely overcome. 

Do not confuse the boll w^eevil with the boll worm, for 
the former is not so easily controlled, but according to Pro- 
fessor Hunter (Bulletin 512, page 11), the boll weevil will 
attack bolls after the supply of squares has been exhausted and 
do great damage. (Bulletin No. 731, page 9, by Professor 
B. R. Coad.) 

CONCERT OF ACTION 

As the boll weevil travels about fifty miles each year it 
can be readily seen that the effort to control must be uniform 
and general in scope. If not, then the cotton planter must go 
through the same processes of applying the syrup and calcium 
arsenate every spring while the cotton is young, using at least 
three applications in all for each year. But by concert of action 
all over the cotton belt it is my belief that the weevil would 
soon become as the once destructive army worm is considered 
today, a mere item in history. 

]3 



DO NOT FOOL YOURSELF 

It matters not if you rotate your crop from corn to cotton. 
Roots of corn stalks form a great hibernating base for weevils. 
Large weeds, pines, and other trees, furnish shelter for them 
during the rigors of winter. They can fly for miles before a 
brisk wind. It is easy for them to make a flight of several 
hundred feet every few minutes, so do not be lulled into in- 
activity and slack defense by supposing that the weevil may 
not visit your cotton next year. The worst crime any man 
can commit against himself is "to fool himself" at any time 
about anything. The farmer who does not study up on the 
weevils and make a close study of how to destroy them, is 
doing himself a gross injustice and in fact is working hard only 
to give them seventy-five per cent of the labor and cost of 
making his crop of cotton. 

WANT OF THOROUGH STUDY 

It is my opinion that the cotton farmer has never given 
the matter of using syrup and molasses as a base for applying 
calcium arsenate the careful consideration that it deserves, and 
the object of this pamphlet is to enable him to form his own 
conclusions as to w^hy syrup (or molasses) and calcium arsenate 
has not come into general use. (The answer being the use 
of the wrong kind of syrup and molasses and of adulterated 
or worthless calcium arsenate.) I feel sure that after a care- 
ful perusal of these pages that every cotton farmer in the 
South will enter into a concert of action to control the weevil 
the coming season through the use of syrup (or molasses) and 
calcium arsenate, and by cleaning up all ditch banks and turn- 
ing rows and burning them off in the early spring. 

I stand ready at all times to help those who wish to help 
themselves and to answer any questions to the best of my 
ability. 

That I champion the use of the molasses or syrup methods 
of using calcium arsenate to control the boll weevil and am 
expending a part of my salary, to place the facts as I see them, 
before the people of our Southland, is sufficient evidence of 
the great interest that I take in this subject which I believe 
means so much to every man dependent upon cotton for his 
daily bread. This includes the banker, the planter, the mer- 
chant, the small farmer, and every one who is depending upon 
the success of the cotton crop. 

I have no syrup, molasses, nor machinery to apply dusted 
calcium arsenate for sale and am not interested in the sales of 

14 



any of them. Hence, hoped-for sales profits from these items 
cannot influence my argument. 

I want an acknowledgment from every reader of this 
treatise showing that you have read and carefully studied the 
facts presented herein. Also opinions and suggestions, and 
especially your experiences with any method of combating the 
boll weevil are earnestly desired. They will be of great help 
to me in my warfare against this enemy. 

Yours for service in Dixie,

N. B. — In compiling this treatise, I have gained much 
information from the following: Bulletin 731 by Professor 
B. R. Coad; Bulletin No. 139 by Professor R. W. Harned; 
"Boll Weevil Problem" by Professor W. D. Hunter; Bulletin 
No. 512; D. A. Bulletin 832; and many other helps from the 
department of Entomology; and from numerous reports of 
farmers who have tried out the syrup and calcium arsenate 
mixture. 



ADDENDA 

Page 9, under head of "WHEN TO APPLY," says: "When 
the cotton is from ten to twenty-four inches high," which is about 
right in extremely rich soils, but for uplands and ordinary soils 
the plant should be from about six to ten inches high, at first appli- 
cation, depending upon the formation of young squares. 

Page 11, in "SYRUP AND CALCIUM ARSENATE AN 
ATTRACTION," the writer had in mind results obtained by cer- 
tain experiments with a compound called "Weevilnip," which is 
used very much like the syrup and calcium arsenate mixture. In 
fact "Weevilnip" is a patented formula which is mixed with the 
syrup and calcium arsenate. The syrup and calcium arsenate 
alone w^ill attract the weevils only a few^ feet, but any attractive 
poison is. much better than a repelling poison.
